Question 13: About how many months did you advance to get to this configuration? (it will be between two months, so just use the half month in between, e.g. between 1 and 2 would be 1.5 months, etc.) Question 14: How many years (in decimal) did it take for this period (divide the number of months you got by 12)?

Using the PC planetarium program “Stellarium”, you will use the

Question Using the PC planetarium program “Stellarium”, you will use the program to find the planets in the current sky, then go outside and observe and report on them.Procedure: This assignment makes use of the free Planetarium software called Stellarium, found at www.stellarium.org. Print out the Stellarium help file (window F1) and refer to it as you work through this assignment. You are asked to save this assignment as an RTF file and submit in the drop box. Set the location to Middle Tennessee using the coordinates listed here, or choose Nashville, TN from the location list in Stellarium.Location: _____Middle Tennessee_____________________________________ Latitude: ___35_ deg. ________0_ min. (N/S?) _N_____Longitude: _______86__ deg. _______0_ min. (E/W?) _W_____ Set the FOV (with mouse wheel) to approximately 100 degrees and face South. Turn on the constellations with F4, choosing markings: check constellation figures (v), names (c), and boundaries (b). Turn off the atmosphere (the A key). This will make the background constellation behind the Sun readable. Turn on the ecliptic line (the comma key). Use the up/down arrows to center the ecliptic on the screen. Open the date and time box and move it to the upper right corner of your screen. Set the time for noon today. Adjust the time until the Sun is highest, about noon, while facing due south.4. Date of Observations (month, day, and year): __July 11, 2019 ________________5. Record the name of the constellation in which the Sun resided: ________________________6. Record the Sun’s Right Ascension and Declination by clicking on it. RA: ____ hours ______ minutes Declination: ______ degrees _____ minutes (N/S?) 7. Now let’s look along the ecliptic to find the planets visible in the sky this evening and tomorrow morning; indicate what constellation and position they were in, then if they are far enough away from the sun’s glare, observe them and report your observations below. Make sure the Atmosphere option is enabled. This will allow you to see if the planet is visible even with the glare of the Sun.Moon was in ____________________________ at RA ____ h ____m, Dec. ____ deg ____’I observed it at ________________ and its phase was _______________________________.ASTR 1030 Observe the Planets with Stellarium Page 2 Mercury was in _______________________________ at RA ___ h ____m, Dec. ____deg., ___ Was it too close to sun to observe currently? _________ If so, skip to Venus, if not, I observed it at __________ looking in the direction ______________________________.  How easy was it to observe? ______________________________________________________Venus was in _______________________________ at RA ___ h ____m, Dec. ____deg., ___Was it too close to sun to observe currently? _________ If so, skip to Mars, if not, I observed it at __________ looking in the direction ______________________________.  How easy was it to observe? ______________________________________________________Mars was in _______________________________ at RA ___ h ____m, Dec. ____deg., ___Was it too close to sun to observe currently? _________ If so, skip to Jupiter, if not, I observed it at __________ looking in the direction ______________________________.How easy was it to observe? _____________________________________________________  Jupiter was in _______________________________ at RA ___ h ____m, Dec. ____deg., ___Was it too close to sun to observe currently? _________ If so, skip to Venus, if not, I observed it at __________ looking in the direction ______________________________.  How easy was it to observe?_______________________________________________________ Saturn was in _______________________________ at RA ___ h ____m, Dec. ____deg., ___Was it too close to sun to observe currently? _________ If not, then I observed it at __________ looking in the direction ______________________________.  How easy was it to observe? ______________________________________________________

Use the Date/Time Window to reset the date to 2010/1/10

Question Use the Date/Time Window to reset the date to 2010/1/10 and the time to 17:00:00 . Using the Location Window, set the location to “Solar System Observer”. You are now looking down on the plane of the Ecliptic. From here we can observe the orbits of the inner planets Use the Search Window to select the Sun. Note the current position of Venus relative to the Sun Question 10: What is the term for the currently set relationship between the Earth, Sun and Venus? Now use the Date/Time Window to advance the date by one month. Notice that as you advance the time, that all the planets move, not just Venus. Now continue to advance the date in one month increments until the Sun, Earth and Venus are once again close to alignment. Question 11: What is the term for the currently set relationship between the Earth, Sun and Venus? ______________________________________ Question 12: About how many months did you advance to get to this configuration? ____________________ Use the Date/Time Window to reset the date to 2010/1/10 and the time to 17:00:00 . Again, note the position of Venus. Advance the date in one month increments until Venus returns to a point close to the same location (relative to the Sun), but just past. Now backup one month. Question 13: About how many months did you advance to get to this configuration? (it will be between two months, so just use the half month in between, e.g. between 1 and 2 would be 1.5 months, etc.) ____________________ Question 14: How many years (in decimal) did it take for this period (divide the number of months you got by 12)? ____________________ Using the actual values for Venus: Orbital = 0.62 years Synodic = 583.92 days and using Equation 1. to calculate % error. Question 15: What is your percent error for the Orbital period? Question 16: What is your percent error for the Synodic period? ____________________ Exercise Materials ((Measured value – Actual value)/Actual value) x 100%
